Temperature difference after the heating cycle from the sea ice mass balance buoy DTC54 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC54 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 01 September 2020.

Description
Summary:Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC54 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 01 September 2020. The thermistor chain was 5.12 m long and included sensors with a regular spacing of 2 cm. The initial ice thickness was 1.76 m, the snow thickness was 0.00 m, and the pond depth was 0.18 m. The resulting time series describes the evolution of temperature during the heating cycle of 20 s and after the heating cycle during the following 40 s as a function of geographic position (GPS), depth, and time between 01 September 2020 and 20 September 2020 in sample intervals of 6 hours. It also contains manually estimated positions of air-snow, snow-ice, and ice-water interfaces. The DTC was installed in the ponded ice next to the ridge and the snow buoy 2020S108: doi:10.1594/PANGAEA.937176.
